powerpc: Remove optimized finite
The powerpc finite optimization do not show much gain:
- GCC will call libm iff -fsignaling-nans is used. This usage pattern
is usually not performance oriented and for such calls PLT overhead
should dominate execution time.
- The power7 uses ftdiv to optimize for some input patterns, but at
cost of others. Comparing against generic C implementation built
for powerpc64-linux-gnu-power7 (--with-cpu=power7):
- Generic sysdeps/ieee754 implementation:
"isfinite": {
"": {
"duration": 5.0082e+09,
"iterations": 2.45299e+09,
"max": 43.824,
"min": 2.008,
"mean": 2.04167
},
"INF": {
"duration": 4.66554e+09,
"iterations": 2.28288e+09,
"max": 35.73,
"min": 2.008,
"mean": 2.04371
},
"NAN": {
"duration": 4.66274e+09,
"iterations": 2.28716e+09,
"max": 34.161,
"min": 2.009,
"mean": 2.03866
}
}
- power7 optimized one:
"isfinite": {
"": {
"duration": 4.99111e+09,
"iterations": 2.65566e+09,
"max": 25.015,
"min": 1.716,
"mean": 1.87942
},
"INF": {
"duration": 4.6783e+09,
"iterations": 2.0999e+09,
"max": 35.264,
"min": 1.868,
"mean": 2.22787
},
"NAN": {
"duration": 4.67915e+09,
"iterations": 2.08678e+09,
"max": 38.099,
"min": 1.869,
"mean": 2.24228
}
}
So it basically optimizes marginally for normal numbers while
increasing the latency for other kind of FP.
- The power8 implementation is just the generic implementation using
ISA 2.07 mfvsrd instruction (which GCC uses for generic implementation).
So generic implementation is the best option for powerpc64le.
Checked on powerpc-linux-gnu (built without --with-cpu, with
--with-cpu=power4 and with --with-cpu=power5+ and --disable-multi-arch),
powerpc64-linux-gnu (built without --with-cp and with --with-cpu=power5+
and --disable-multi-arch).
